Claims. (Cl. 1851-73) The principal object of this invention is to provide an improved sash guide which can be readily adjusted to eifect a correct sliding t of a sash in a window opening even though the opening be 5 found to be oversize or out of true.

Other more specific objects and advantages of the invention will be apparent to those skilled in the art upon a full understanding of the construction, arrangement and manner of use of the improved guide.

A preferred embodiment of the, invention is presented herein for the purpose of exemplication, but it will of course be appreciated that the invention may be incorporated in other struc- ]5 turally modified forms coming equally within the scope of the appended claims.

In the accompanying drawing:

Fig. 1 is a fragmentary perspective View of a guide constructed in accordance with the invention, with a sash slidably mounted in the guide and with the guide secured to one of the side posts of a window opening;

Fig. 2 is a partially sectioned side view of the guide, sectioned on the line 2-2 of Fig. 3;

Fig. 3 is a partially sectioned face view of the guide, sectioned on the line 3 3 of Fig. 2;

Fig. 4 is a horizontal section through the guide, taken on the line i--II of Fig. 2, showing the side rail of the sash in place;

3G Fig. 5 is a similar View, showing the guide after it has been adjusted to conform to a wider window opening; and

Fig. 6 is a vertical section, taken through the guide on the line 6 6 of Fig. v2, at the location of one of the adjusting devices.

The improved guide consists of a stationary strip I0 and a. movable strip I I. The stationary strip is adapted to be attached by screws I2 to a post I3 at one side of the window opening,

while the movable strip, which is carried by the stationary strip, is adapted to engage with and form a guide for the bearing portion I4 of the adjacentside rail I5 of the sash.

As the invention resides in the construction of the guide, without regard to the character of the post or sash, only a small portion of one side of the sash has been shown. The other side of the sash is of course slidably mounted in another guide, which second guide is preferably, though not necessarily, constructed in accordance with the invention.

In the particular embodiment shown, the strips I 0 and II are both made of sheet metal. The strip I0 is U-shaped in cross section and opens toward the edge of the sash. The back I6 of the strip is positioned flatly against the post.. I3 and is apertured at intervals for the reception of the attaching screws I2. The side flanges I'I and I8 of the strip project from the back I6 in spaced parallel relation to each other, with the 5 flange I1 projecting considerably farther, however, than the iiange I8.

'I'he strip I I, together with a readily removable retaining strip I9 which is carried by it, presents a formation which is approximately H-shaped in 10 cross section. 'I'he back or cross-web portion 20 of the strip II is arranged in adjustably spaced parallel relation to the back I6,of the strip I0. On that side of the strip II which corresponds to the wide flange I1 on the strip I0 a flange 2| l5 projects away from the back 20 toward the sash and terminates in a reversely bent flange 22 of considerably greater width, leaving a deep narrow slot 23 between the flanges 2I and 22. On the other side of the strip II a flange 24 projects in 20 the opposite direction toward the back I6 of the strip I0 and terminates in a reversely bent ange 25 of the same width, leaving a relatively `open groove 26. Y

The retaining strip I9, which is adapted to bear 25 against one face of the bearing portion I4 of the sash, in opposition to the flange 2| at the other face of the bearing portion, is seated in the groove 26 and is pressed resiliently against the bearing portion I4 by the action of a thin spring 30 strip 21 which is secured to the strip I9 and is located within the groove. The strip I9 is detachably held in position in the groove by any suitable means.

The strip II is nested with the strip I0, with 3l the ange I'I of the strip contained within the slot 23 and with the ange I8 of the strip ID positioned against the ange 25 of the strip I I. The slot 23'is preferably, though not necessarily, of initially smaller width than the thickness of the 40 flange Ii', so as to effect a snug spring-pressed engagement therewith, and the flange I8 of the strip I 0 is also preferably, though not necessarily, turned in initially a little toward the iiange I'I, for the same purpose. With the strips II) and I I 45 nested together in the manner described, there is no possibility of air, water or dust getting through between the same.

To adjust the strip II toward or away from the strip Ill, a plurality of screws 28 are em- 50 ployed, which screws are threaded either into the post I3, or into the back I6 of the strip I Il, or into some member carried by the strip I0 or the post I3. The heads 29 of the screws 28 set iiush in straight cut apertures in the back 20 of the 55 strip Il, and just behind the back 2|! the shanks of the screws 28 are provided with enlarged annular ribs 30, which ribs are confined between the back and the plates 3| through which the screws extend. The plates 3| extend parallel with the back 20 and are provided at their far ends with small flanges 32 which abut with the back and function as fulcrums for the plates. Between the screws 28 and the fulcruming flanges 32 are located conical head screws 33 which extend loosely through conical apertures in the back 20 into threaded engagement with the plates. The portions of the backs 20 against which the ribs 30 are adapted to be clamped are preferably serrated a little, as shown at 34, in order to increase the frictional engagement at that point.

When the screws 33-which may be termed the locking screws in order to differentiate them readily from the adjusting screws 28-are tightened, the screws 28 cannot be turned because the ribs 30 on the same are thereby clamped against rotation, but when the screws 33 are loosened a little, the screws 28 can be turned whereby to cause either or both ends, as desired, of the strip H to be moved toward or away from the strip l0 to "obtain just the right amount of clearance or contact needed with respect to the bearing portion I4 of the sash.

It will of course be understood that when this improved adjustable guide is applied to the post an interposed layer of any suitable sealing matei-iai, such as cement, felt or rubber, will ordinariiy be used to insure a weather-tight connection with the post. If desired, the contacting portions of the strips III and Il may be surfaced with any suitable weatherproong material, such as thin felt, which must not interfere, however, with the strip Il being adjusted toward or away from the strip I0.

I claim:

l. In a sash guide, a xed strip for attachment to a post at one side of a window opening, an adjustable strip carried by the xed strip for sliding coaction with one side of a sash in the opening, a screw rotatable in either direction to cause movement of the adjustable strip toward or away from the iixed strip, and means for locking the screw against rotation in any position of adjustment of the strip.

2. In a sash guide a fixed strip for attachment to a post at one side oi a window opening, an adjustable strip carried by the iixed strip for sliding coaction with one side of a sash in the opening, a screw rotatable in either direction to cause movement of the adjustable strip toward or away from the xed strip, and means for locking the screw against rotation in any position ot adjustment of the strip, said screw being threaded into the xed strip and anchored against atxiial movement with respect to the adjustable s r p.

3. In sash construction, the combination with a window frame, and a sliding sash in the frame, oi.' a guide attached to one side of the frame for engagement with one side of the sash, means for moving the guide toward or away from the sash to compensate for variations in either the width of the frame or the width of the sash, and separate means for locking the guide in any adjusted position.

4. In a sash guide, a xed strip for attachment to a post at one side of a window opening, an adjustable strip carried by the fixed strip for sliding coaction with one side of a sash in the opening, a screw which extends through an aperture in the adjustable strip into screwthreaded engagement with the fixed strip` for moving the adjustable strip toward or away from the iixed strip upon rotation of the screw, an annular rib on the shank of the screw for frictional engagement with the adjustable strip to prevent rotation of the screw, a plate for clamping the rib against the adjustable strip, and means for drawing the plate up against the rib.

5. In a sash guide, a fixed strip for attachment to a post at one side of a window opening, an adjustable strip carried by the fixed strip for sliding coaction with one side of a sash in the opening, and a screw rotatable in either direction to cause movement of the adjustable strip toward or away from the ixed strip, said screw being releasably clamped against the adjustable strip.
